Of Brazilian origins and with decorative virtues appreciated throughout the world, Bouganville is a plant that can be easily grown in every region of Italy. The rules for its cultivation are very simple.
When to proceed with pruning. Advice for correct execution
Like any plant, also the Bouganville (or Bouganvillea), which has a climbing and bushy habit, requires the ordinary operations relating to pruning, so that the plant can breathe better, receive and absorb more light and thus reinvigorate itself.
The best time to carry out this type of operation is autumn, so at the end of the flowering period of this splendid plant, but during the month of February we advise you to prune the branches that are weaker.
The Bougainvillea has the characteristic of growing very fast compared to other plants.
It is therefore necessary to make significant cuts, especially if the growth, during the cold winter months, was more consistent than usual. However, care must be taken to apply the wire on the shoots and not on the part of the wood, because the latter breaks easily. In bosai version, this plant assumes an erect habit, which represents an exception compared to its classic and natural climbing habit.
Where to grow it. The particularities of its flowers
It must be clarified that the flowers of this plant are the smaller, white ones, which are found in the center of a larger part, of a purple color, which many mistakenly think to be an integral part of the flower, that is, petals, whereas they are bracts, that is, leaves that over time have undergone changes. Generally the actual flowers originate precisely from the so-called axillary attachment of the bracts. As for the coloring of the bracts, they can be fuchsia, pink or even orange. The bark is light brown and its branches have many thorns. Due to its characteristics, this plant can be kept in sunny and well-ventilated areas. In the winter months, if you notice that the temperature has dropped excessively, it is advisable to bring the vases inside the houses, to prevent any suffering in the Bougainvillea. In our country, thanks to a particularly favorable climate, it can be cultivated in all regions, with the sole exception of those areas where the climate is too rigid in some months of the year.
Watering and multiplication of the Bougainvillea
Watering of this evergreen climbing shrub should be administered frequently in the summer, taking care not to leave dangerous water stagnation in the soil.
The liquid fertilizer should be delivered throughout the year, but avoiding the flowering period, because it would produce excess production that would lead to serious imbalances in the biological organism.
The ideal soil to cultivate it must be composed of 2/5 sand, 2/5 peat and 1/5 of clay. Inside the pots the soil must be kept well drained and therefore it is advisable to prepare a layer of sand on the bottom of the pots themselves.
Repotting operations can be carried out every 2-3 years, pruning the roots, in early winter.
The multiplication of this plant takes place by taleation, which is carried out by taking wood parts about ten centimeters long during the spring and then placing them in a container with 50% sand and 50% peat, kept moist at a temperature on the 20-25 degrees. Rooting develops within 20 days. The solution of the aerial layering is also practicable.
General information on the Bouganville plant
It belongs to the family of the Nyctaginaceae, order Caryophyllales, is of tropical origins and among the most important species must be the buttiana, the spectabilis, the troli and the valverde. There are a total of eighteen known species. It is widespread in South America and especially in Brazil, where it was discovered in the mid-eighteenth century by Philibert Commerson, a famous French botanist, who decided to give it this name to pay homage to the head of that scientific expedition called Louis Antoine de Bouganville. Due to its peculiar characteristics it is particularly suitable for covering walls and pergolas.
The enemies and diseases of the Bougainvillea. What to do
At the conclusion of our discussion it should be remembered that this plant suffers from the frequent infestations of Cochineals, phytophagous parasites very common everywhere, which can be easily identified by anyone, given that they appear as small brown growths.
In this case we must proceed to the operations of disinfestation of the plants with the use of anticoccidial products. The situation is even more serious if the plant is struck by the disease called ferric chlorosis, which occurs when there is no more chlorophyll formation or insufficient formation. Recognizing the symptoms is very easy, because we will see the rapid yellowing of the green parts. The reasons may be different: from an excess of water stagnation to a real infectious disease that can affect plants.
